Classification. Interactive Behavior. Elements. Degree of Human Intervention. Working / Output. Open. Closed. Abstract. Physical. Manual. Automated. Deterministic. Probabilistic. Interacts freely with environment. taking Input - Returning Output. Change in environment - Change in system. Influenced by elements outside system Boundary. Information Systems. Does not Interact with change in Systems. does not change with change in environment. Finally Run down or disorganized. Movement to disorder is is increase in ENTROPY. Conceptual or Model. Orderly Arrangement. Interdependant Ideas or Constructs. Tangeable Elements. Operate Together. Accomplish Objective. Display activity/ Behavior. Parts interact to achieve Objective. Carried out by Human Efforts. Data Collection. Maintanance. Final Reporting. Computers or Microprocessors are used. to carry out all the tasks. Not 100% automated. Reasons - computers. Predictable Manner. Interaction amongst the parts - Known certainity. Description of - given point plus description. Computer Program according to set of instructions. Probable Behaviour.
